Description:
We present the validation of a multiresidue method for the concurrent SPE of organochlorine (OCP) and phenoxy-acidic pesticides (PA) in river water. The two classes of compounds show very different chemical characteristics. The analyses were performed by gas chromatography–mass spectrometry and by liquid chromatography–electrospray ionization–mass spectrometry. The method was validated at three different concentrations: method limit of quantitation, 0.5 and 5 μg L −1 . The recoveries were in the range 65–135% for all the target compounds and in the range 83–113% with RSD 〈20% for most of them at all the concentrations tested. The method showed good accuracy, precision, and sensitivity, and allowed the analysis of the selected pesticides at a concentration lower than that required by the EU current legislation for surface water [ 1 ]. The single-step procedure reduced artifacts, matrix effects, and speeded up sample preparation.
